LEVER-LOCK.

Specification QtLetters Patent. Patented July 18, 1911.

Application filed August 1.1, 1909. Serial No. 512,296. (Model.)

To all lwhom it may concern:

Be it known ythat l, ALBERT B. Drsnniori, a citizen'of the UnitedStates, and aL resident of Detroit, in "the county of Wayne and State ofMichigan, have invented anew and Improved Lever-Loek, of which thefollowing is a specification.

My invention relates to means for locking levers, especially such ascontrol the operation of automobiles, and its objecty is to provide asimple, strong and eiiicient device whereby unauthorized personsmay beprevented from operating the device controlled. by the lever. l

In the accompanying'drawings Figure 1 is a side elevation of thetransmissionrontrol levers ottone type of automobiles with my improvedlever-lock in posit-ion. Fig. 2 is a cross section on the line 2 2 of l`ig..1. Fig. 3 is a 2. Fig. 4 is a lockingblock- Similar referencecharacters refer to like parts throughout the several views.

In therdrawings the invention is shown embodied in a controlling devicetor a pair of operating levers. The -trame 1 has secured to it a bracket2 in which is j ournaled a sleeve 3 and 'a shaft 4. To the sleeve issecured an' operating lever 5 and to the shaft, an operating lever 6.MountedY on the' shaft is a sleeve 7 carrying a pin 8, on which pin ispivoted the lower end of the controlling lever 9.

The operating levers 5 and 6 have inwardly extending jaws' 10 which areadapted to receive the controlling lever 9 as Vit is swung laterallytoward one or the other. Springs 11 mounted on these operating leversare adapted to hold the lcontrolling lever approximately central. Arms12 on the bracket 2 carry the guide bars 13 and the stop bars 14, the.latter separated by a gap.

rEhe springs 11 normally hold the lever 9 in the gap between the ends ofthe bars 14.

perspective view of the The operating levers 5 and 6 are at neutralposition so'longV as the controlling vlever is in this gap and duringthis time, the inachinery controlled thereby is at rest. The levers 5and 6 are for the purpose ot adjust.-

`ing movable parts, and the controlling lever plan on the line 3--3 ofFig.;

9 is swung laterally 'from neutral position into biet-Ween, the jaws 10of either operating lever as4 desired 'for the urv ose ot' actuan' ingthe selected operating lever. The controlling lever will remain inengagement the sides would operate as well if separate.

To prevent the lock being removed, a hole 17 is formed in thecontrolling lever through which the hasp 18 of the padlock 19 passes.

It the key to the lock is lost, the hasp can be cutoli and a new loch'.substituted.

The construction. of the automobiles to which this lock is adapted issuch that both the levers 5 and 6 cannot move together.

As a rule, one lever can move down to theA left (Fig. l) from thecentral positionand v the other lever down to the right. l In suchconstruction' there is no4 possibility of the two levers 5 and 6 movingtothe left (Fin:

1) and thus carry the cross-bar 16 from blow the padlock.. f

This invention is adapted torv locking devices for levers of aiiydescription, automQ-' biletrans1nission leversbeing -shownsbecause 'oftheir universal use. y

Having now explained my improvements, what I Vclaim as my.' inventionand desire to secure by Letters Patent is: I

1'. In a device of the class described, the combination with a pair ofoperating leve-rs having inwardly-extending jaws, pivots for saidlevers, a controlling lever mounted concentrically with the operatinglevers, parallel guide and stop bars for 'said levers, and

a securing device engaging between the jaws of thev operating levers tohold the controlling lever in engagement with the stop bars. 2. Inadevice of the class described, the

combination of an operating lever .having projecting jaws, a pivot forthe Same, a controlling lever mounted eoneentreally with the operatinglever, parallel guide and stop bars for .said levers, and a securingdevice adapted to engage between the jaws of the operating lever to holdthe controlling lever in ,engagement with the Stop bars.

In testimony whereof I have signed this specicaton in the presence oftwo subscribing witnesses.
